Exposure to Radio Frequency Signals (SAR)
Your wireless phone is a radio transmitter and receiver. It is designed and
manufactured not to exceed the emission limit for exposure to radio
frequency (RF) energy set by the Federal Communications Commission of
the US government and Canada. These limits are part of comprehensive
guidelines and established permitted levels of RF energy for the general
population. These guidelines are based on the safety standards previously
set by both US and international standard bodies.
These standards include a substantial safety margin designed to assure the
safety of all persons, regardless of age and health.
The exposure standards for wireless mobile phones employs a unit of
measure known as the Specific Absoption Rate, or SAR. The SAR limit set
by the FCC and Canada is 1.6W/kg averaged over one gram of tissue.
Tests for SAR are conducted using standard operating positions specified
by the FCC with the phone transmitting at its highest certified power level in
all tested frequency bands. Although the SAR is determined at the highest
certified power level, the actual SAR level of the phone while operating can
be well below the maximum value. This is because the phone is designed to
operate at multiple power levels.
Before a phone model is available for sale to the public, it must be tested
and certified to the FCC that it does not exceed the limit established by
government-adopted requirement for safe exposure. The tests are
performed in positions and locations (for exampe, at the ear and worn on
the body) as required by the FCC for each model. The highest SAR value for
this phone when tested for use at the ear is 0.076W/kg, and when worn on
the body is 0.018Wkg. (Body worn measurements differ among phones
depending upon available accesories and the FCC requirements.) While
there may be differences between the SAR levels of various phones and at
various positions, they all meet the government requirement for safe
exposure.
For body worn operation, to maintain compliance with FCC RF exposure
guidelines, use only Ascom approved accessories. When carrying the
phone while it is on, use only the specific Ascom belt clip that has been
tested for compliance.
Use of non-Ascom-approved accessories may violate the FCC RF exposure
guidelines and shoud be avoided.
The FCC has granted an equipment authorization for this Ascom 9p23
phone with all reported SAR levels evaluated as in compliance with the FCC
RF emissions guidelines. SAR information on this 9p23 phone is on file with
the FCC and can be found under the Display Grant section of
http://www.fcc.gov/oet/fccid after searching on FCC ID 04M9p23.
